IMPROVEMENT IN INSTRUMENTS FOR NOTCHlNG PATTERNS.

Specification forming part of Letters Patent N0. 1 72,531, dated January18, 1876; application filed December 28, 1875.

tion in the plane y y, Fig. 1. Fig. 4: is a sideview of the hollowstandard. Fig.5is a plan of a pile of patterns, showing the notches ormarks produced by my implement.

Similar letters indicate corresponding parts.

This invention relates to an improvement on that class of implements fornotching patterns of garments which I have described in my Patent No.169,066, dated October 19,1875, and which consists essentially of afoot-plate supporting a hollow slotted standard with a plungerreciprocating vertically within the standard, provided with a knifeprojecting beyond and through the slotted standard.

'My present improvement consists in combining with the foot-plate, thehollow standard, and the vertical]y-reciprocatin g plunger a knife witha V-shaped or U-shaped cutting-edge, the loose end of which is guided ina groove in the slotted standard, and the cutting-edge of whichco-operates with a receiver in the foot-plate of corresponding shape, sothat the patterns after having been cut out can be pro vided withplainly-visible marks which form guides in the operation of finishingthe garments.

In the drawing, the letter A designates the foot-plate of my implement,which is, by preference, made circular, with a flat bottom and a convextop, its edge being sharp, so that it can readily be pushed beneath thepile of patterns to be operated upon. Said foot-plate may, however, bemade in any other convenient form or shape. From the center of saidfoot-plate rises a standard, B, which is bored out to receive theplunger 0 and also a spring, D, that serves to force the plunger up. Tothe upper end of said plunger is secured a handle, E, which serves todepress the same against the action of its spring, said handle being soformed that it extends over the outer surface of the standard B, andassists in keeping the plunger steady. To the bottom end of said plungeris secured a knife, F, which extends through slots at a in the standardThe outer ends of this knife are bent so that their cutting-edges becomeV-shaped or U- shaped, and the free ends of said knife are guided ingrooves'b b provided for their reception in the standard B. In thebottom flange of said standard are formed receivers c c, whichcorrespond in shape to the cuttingedges of the knife, and into whichsaid cutting-edges drop When the plunger is depressed. These receiversare formed by steel plates 01 d, which are secured to the foot-plate,(see Fig. 3,) and which form sharp edges to co-operate with thecutting-edges of the knife.

By these means 1 am enabled to cut clear through a pattern .or a pile ofpatterns without difficulty, and I- am enabled .to produce semicircularor V'shaped notches or marks in a pile of patterns or in a singlepattern, (see Fig. 5,) and such marks are clearly visible, so that theyform safe guides in finishing the garments for which the patterns areintended.

I disclaim in this application for a. patent everything shown anddescribed in my Patent No. 169,066.

What I claim as new, and desire to secure by Letters Patent, is

1. In an implementfor notching patterns of garments, a knife with aV-shaped or a U- shaped cutting-edge, in combination. with a foot-plate,a hollow slotted standard, and a reciprocating plunger, the standardbeing pro- I vided with a groove-guide for the free end of the knife,substantially as shown and described.

2. The combination, with a knife having a V-shaped or U-shapedcutting-edge, with the hollow slotted standard and with the footplate,of a receiver, a, corresponding in shape to the cutting-edge of theknife, substantially as set forth.

In testimony that I claim the foregoing I have unto set my hand and sealthis 18th day of December, 1875. I
